ARTIFICIAL SHINGLE.

To all whom it may concern:

Be it known that we, SIMEON BUSH CHRISTY, a citizen of the United States, and a resident of Murfreesboro, in the county of Rutherford and State of Tennessee, O'I'ro MILTON LONG, a citizen of the United States, and a resident of Bowling Green, in the county of Warren and State ofKentucky, and FRED RICHARDSON BREN'IS, a citizen of the United States, and a resident of Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Artificial Shingles, of which the following is a specification.

This invention relates to artificial shingles and has for its object a product and process for forming the product from rock asphalt.

Shingles have been made of a mixture of liquid or viscous asphalt which has been heated suiciently to get the proper miscibility of the asphalt and then pressed into shape by any wellknown means. Reinforcin elements have been added to the asphalt eit er by running the reinforcing means through liquid as halt or by pressing the same Into the me ted asphalt when in the process of forming the shingles.

It is an object of our invention to form a shingle of asphalt without the use of heat and 1n which the shingle is formed of finely ground rock asphalt which is pressed to the desired thickness whereby the shingles may be readily handled without breaking and when applied to a roof will be more durable than the artiicial shin les now in use.

Other objects and a vantages will become apparent during the course of the following description.

The invention is illustrated by way of example in the accompanying drawings, in

which,

Figure 1 is a view in perspective of the shingles applied in overlapping relation to a roof.

Figure 2 is a transverse section of a shingle showing the manner of reinforcing the same.

Figures 3 and 4 show transverse sections disclosing other modifications of the reinforcement.

In order to form the basic shingle, we halt 9 f mel an Il Il' g l u i u to form a shmgle 'of suliicient th1 iexibility that will be very durable. Th rock asphalt meal may be, rolle instead of being compressed to the er size into Hat sheets and the same may be cut in desired lengths and widths and where desired the sheets may be employed alone for roofing pur oses.

T e natural rock asphalt is employed as obtained from its natural formation 1n this and other countries and is therefore not a composition as is commonly employed in the construction of artificial shingles. Articial .colorin matter and cements of differen r1n s y` e employed as desired together with any form of reinforcing element to add to-the strength of the roof shingle, tiling or insulation.

Referring more particularly to the drawrl ings, 1 indicates an asphalt shingle which is laid in overlapping relation and 1s formed of ground rock asphalt compressed to the desired thickness. Any form of reinforcing may be employed such as a sheet of asbestos 2 shown in Figure 2, the sheets being spaced from each other and with an intermediate reinforcing wire fabric 3.

The reinforcing sheets may be dis ensed with and a wire fabric 4:, disclosed in igure 3, of the shingle lb may be employed.

In Ficfure 4 a still further modified form of shinglle lc is disclosed with a single sheet of the reinforcing element 2. The wire fabrics of Figures 2 and 3 as shown more clearly in Figure 1, are embedded in the compressed asphalt of the shingle.

In Figure 1 part of theY shingle 1 is cut away to disclose the sheet of asbestos 2 embedded in the compressed Vground rock asphalt.v

The `fgllmfwnemployed in the construction o e s ingle is a pure siliclous sand thoroughly impregnate w1 'mi pa t. sbestos may be employe 1n e ne y v1 as forming art of the completed shingle or the shin formed by using a as halt and e may be10o It has been found by actual experiment compressed in -tlle Mformmof tiling and emthat the compressed rock asajlilt forms a p10 ed as such.
